A slow internet connection is one of the most frustrating tech problems, especially when you're trying to work, stream, or game. If you're wondering how to fix slow internet, you're not alone — it's one of the most common tech support questions. This guide covers 12 proven solutions that address the most common causes of slow internet, from quick fixes to advanced troubleshooting.
Quick Fixes (Try These First)
1. Restart Your Router and Modem
The classic "turn it off and back on" works more often than you'd expect. Unplug your router and modem, wait 30 seconds, then plug the modem back in first. Wait for it to fully connect, then plug in the router. This clears the device's memory and re-establishes your connection.
2. Run a Speed Test
Before troubleshooting, know your baseline. Visit speedtest.net or fast.com and test your speed. Compare the results to what you're paying for. If you're paying for 100 Mbps but getting 10 Mbps, there's clearly a problem. If you're getting close to your plan speed, you may need a faster plan rather than a fix.
3. Switch to Ethernet
Wi-Fi adds overhead and interference. If possible, connect your device directly to the router with an ethernet cable. If speeds are normal on ethernet but slow on Wi-Fi, the problem is your wireless connection, not your internet service.
Optimize Your Wi-Fi Connection
4. Move Your Router to a Central Location
Router placement dramatically affects Wi-Fi performance. Place your router in a central location, elevated off the floor, away from walls and metal objects. Avoid placing it near microwaves, baby monitors, or other electronics that can cause interference.
5. Switch to the 5 GHz Band
Most modern routers broadcast on two frequencies: 2.4 GHz and 5 GHz. The 5 GHz band is faster but has shorter range. If you're close to the router, switch to 5 GHz for better speeds. Check your Wi-Fi settings for networks ending in "_5G" or similar.
6. Change Your Wi-Fi Channel
In apartments and dense neighborhoods, multiple routers compete on the same channel. Use a Wi-Fi analyzer app to find the least congested channel, then change your router's channel in its settings (usually accessible at 192.168.1.1 or 192.168.0.1).
Identify Bandwidth Problems
7. Check for Bandwidth Hogs
Other devices or applications on your network may be consuming bandwidth. Common culprits include:
- Cloud backups running in the background
- System updates downloading
- Streaming on multiple devices simultaneously
- Security cameras uploading footage
- Other family members gaming or streaming
Check your router's admin panel to see which devices are using the most bandwidth.
8. Enable QoS (Quality of Service)
QoS is a router feature that lets you prioritize certain traffic. For example, you can prioritize video calls over file downloads, ensuring smooth meetings even when others are using the internet. Access this in your router settings.
Advanced Troubleshooting
9. Update Router Firmware
Outdated firmware can cause performance issues and security vulnerabilities. Log into your router's admin panel and check for firmware updates. Most modern routers have an auto-update option you can enable.
10. Change Your DNS Server
Your ISP's default DNS servers may be slow. Switching to a faster DNS can improve page loading times:
- Google DNS: 8.8.8.8 and 8.8.4.4
- Cloudflare DNS: 1.1.1.1 and 1.0.0.1
- OpenDNS: 208.67.222.222 and 208.67.220.220
You can change DNS on your router (affects all devices) or on individual devices in network settings.
11. Check for ISP Throttling
Some ISPs throttle speeds during peak hours or for certain types of traffic (like streaming). Test your speed at different times of day and with a VPN. If speeds are normal with a VPN but slow without, your ISP may be throttling specific traffic.
12. Contact Your ISP
If nothing else works, the problem may be on your ISP's end. Issues like old infrastructure, area outages, or line problems require your ISP to fix. Before calling, have your speed test results ready and note when the problem occurs.
When to Upgrade Your Equipment
Sometimes the fix is new hardware:
- Router age: If your router is over 3-4 years old, upgrading to a Wi-Fi 6 or Wi-Fi 6E router can significantly improve speeds
- Mesh systems: For large homes, a mesh Wi-Fi system (like Google Nest, Eero, or TP-Link Deco) eliminates dead zones
- Internet plan: If you consistently need more speed than your plan offers, it's time to upgrade
Frequently Asked Questions
Why is my internet slow only at night?
Evening slowdowns are usually caused by network congestion. Your ISP's infrastructure is shared among users in your area, and peak usage (typically 7-11 PM) can reduce speeds. If this is a persistent issue, contact your ISP or consider switching to a provider with less congestion.
Does having too many devices slow down Wi-Fi?
Yes, but it depends on your router and internet plan. Modern routers can handle dozens of devices, but if many devices are actively using bandwidth simultaneously, speeds will decrease for each device. Upgrading to a better router or higher-speed plan can help.
Should I use a Wi-Fi extender or mesh system?
Mesh systems are generally better than extenders. Wi-Fi extenders can halve your speed because they rebroadcast the signal, while mesh systems create a unified network that maintains better speeds throughout your home. If budget allows, go with mesh.
How fast should my internet be?
It depends on usage. For basic browsing and email, 25 Mbps is sufficient. For streaming 4K video, aim for at least 50 Mbps. For households with multiple users streaming, gaming, and working from home, 200-500 Mbps provides a comfortable buffer.
Conclusion
Fixing slow internet usually starts with simple solutions — restarting your router, checking for bandwidth hogs, and optimizing Wi-Fi placement. If those don't work, try changing DNS servers, updating firmware, or checking for ISP throttling. Most internet speed problems can be resolved without calling your ISP or buying new equipment. However, if your router is outdated or your plan simply doesn't provide enough speed for your household's needs, upgrading may be the best long-term solution. Start with the free fixes in this guide and work your way down until you find what solves your specific issue.
